I’ve been doing these “prototype for billboards at A-Z West” for about seven years now. They are painted on 4×8 sheets of plywood – I believe that there are images of earlier versions posted on my website. They initially began as advertisements or illustrations for a series of principles that I’ve been working on called “these things I know for sure” – more recently though the billboards have been going in other various directions. (The more recent ones depict “bodies in space with objects” There is a very nice text about them in the book that I did for my exhibition at Schaulager – I believe that the title of the book is just my name “Andrea Zittel”.
